Sadly not all parents are responsible with why they are given.
I know personally people in the same situation who get the same benifits etc and one is always borrowing money and going out etc and seems to struggle and others with the same income and number of kids seem to manage just fine.
People definitely need help and I am glad that there is help out there, my parents weren't particularly well off growing up and a lot of us know it can be a struggle, but I agree, there was nothing wrong with that particular comment. Parents should, where they can, look after their own ****ing kids.
